Ask your doctor. We have no idea what surgery you had or what your workout entails.
I have had a surgery 2 months back, Can I get back to my workout now?
Follow your doctor's take home instructions, If you misplaced them call his/her office and the nurse can give you another copy.
No workout til you have a full clearance possibly in writing from your doctor.
That is a question only your doctor can answer. With that said, with any surgery have had, at 2 months when I was allowed to start, I had to start with restricted movements and could only do abbreviated beginner workouts.
